StardewUI menus do not respect the Menu Backgrounds in-game setting

[pneuma163]

The setting Menu Backgrounds changes how the space around a menu appears. The setting can be Standard (a transparent dark overlay), None (none, added in 1.6), or Graphical (a seasonal image).

Opening a menu created from an .sml asset notably creates a much darker semi-transparent overlay on the Standard setting and does not include the seasonal image on the seasonal setting. The None setting works as expected.

The opacity (darkness) is configurable through the menu controller.

I thought the seasonal backgrounds were menu-specific but I'll take a look to see if there's a standard.

I'm creating my menus via an .sml asset and don't know anything about changing anything with the menu controller (it wasn't in the docs that I saw back when I started this several months ago) so I had assumed that this difference from vanilla menus was on StardewUI's end via whatever defaults it sets for the opacity and graphics, hence why I reported this as a bug. I only noticed it recently because I exclusively use the "None" setting in the game options.
